Description

  The present invention relates to a broadcast signal transmission system that automatically selects content material according to a predetermined schedule and transmits it as a broadcast signal in a broadcast station studio system that produces a news program, for example.

  As is well known, in broadcasting stations, various content materials such as CMs (advertisements) / programs / provided guides are put on a commercial bank device, VAF (video / audio file) device, VTR (video tape recorder), etc. Stored in the content storage device. Then, in the broadcast transmission system, predetermined contents are sequentially read from a plurality of content storage devices according to a predetermined schedule from a DS (Data Server) device and an APC (Automatic Program Control) device, and are selectively derived by a switching device. Thus, it is configured to transmit as a one-channel broadcast signal.

  In particular, in broadcasting station studio systems that produce news programs, as a broadcast signal transmission system that is the final exit of video, in addition to a master transmission system for on-air fixed content programs, news production for variable content reports, etc. A subsystem is prepared as a system. Program organization (program frame, CM entry time, etc.) is on-air controlled according to a schedule determined by the DS (Data Server) device and APC device on the master transmission system side, and the program is passively executed in the subsystem. It is a mechanism that fills the frame with news.

  However, in order to create a program that is easy to produce and attractive in the production of news, which changes in content and progress from moment to moment, instead of creating a program within the limits of the frame determined by the master transmission system, There is a growing demand for a mechanism for easily and flexibly changing the program organization according to the contents of the program. Until now, it has been difficult to flexibly change the program organization according to changing news contents and progress.

The outline of the program production / sending device related to the present invention is described in Patent Document 1.
Japanese Patent Laid-Open No. 10-276157

  As described above, in the conventional broadcast signal transmission system, a subsystem is prepared as a news production system for variable content reporting below the main system for fixed content programs. Even though there is a demand for a mechanism to easily and flexibly change the program organization, it is forced to create programs within the limits of the frame determined by the master transmission system, and according to changing news content / progress, It was difficult to change the program organization flexibly.

  An object of the present invention is to solve the above-mentioned problems and to provide a broadcast signal transmission system having a mechanism for easily and flexibly changing the program organization, for example, for news such as news whose contents and progress change from moment to moment. To do.

  In order to achieve the above object, the present invention provides a broadcast signal transmission system that reproduces the content of each program based on the program organization information at a specified time and selectively transmits the content as a broadcast signal, based on the program organization information. The first transmission device that normally executes the content transmission control, and the transmission control is transferred from the first transmission device as required, and a special program frame is created based on the basic program frame of the program scheduling information And a second transmission device that executes transmission control of an arbitrary content in the special program frame, and transfers the transmission control to the first transmission device after the special program frame ends. .

  According to the above-described invention, the transmission control is normally executed by the first transmission device, and when special program broadcasting is required, the transmission control is transferred to the second transmission device, and the program frame is appropriately changed. Content transmission control can be executed. Thus, for example, a broadcast signal transmission system having a mechanism for easily and flexibly changing the program organization for a program such as news whose contents and progress change from moment to moment can be provided.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing an embodiment of a broadcast signal transmission system according to the present invention. In FIG. 1, reference numeral 11 denotes an EDPS (business broadcasting system). This EDPS 11 is used to determine a program frame in a time zone, and to create program organization information that determines content materials to be broadcast in each program frame and a transmission time thereof. Thus, the program scheduling information created here is sent via the DS device 12 to the normal program master sending device 13 and the news master sending device 14 which is in the same relationship with the master sending device 13.

  In the normal program master transmitter 13, reference numerals 131 and 132 denote an information LAN and a control LAN, respectively. Program scheduling information sent from an EDPS (business broadcasting system) 11 through a DS (data server) device 12 is input to an APC device 133 through an information LAN 131. The APC device 133 specifies the content at a predetermined timing based on the program scheduling information, and plays back the VTR 134, the CM bank device 135, and the VAF device 136 through the control LAN so that the predetermined content is transmitted at the transmission time. The content read by the master switcher 137 is selectively derived as an on-air signal.

  On the other hand, in the news master transmitter 14, reference numerals 141 and 142 denote an information LAN and a control LAN, respectively. Program scheduling information (here, only basic information on program frames) sent from an EDPS (business broadcasting system) 11 through a DS (data server) device 12 is taken into the news DS device 143. The news DS device 143 transfers the sending control from the normal program master sending device 13 to the news master sending device 14 in response to the operator's start instruction input, and in response to the end instruction input, the news master sending device 14. To return the transmission control to the normal program master transmission device 13. Then, program frames are arbitrarily assembled, and contents selection instructions and transmission times used in the respective program frames are set in the news APC device 144.

  The news master transmission device 14 includes an imaging camera 145 for live broadcasting and a VTR 146 that records news material. In the news APC device 144, the devices 145 and 146 and the devices on the normal program master transmission device 13 side are provided. 134 to 136 also enable playback control. The read output of the devices 145 and 146 in the system 14 is selected and output by the news transmission switcher 147 under the control of the news APS device, but this output is sent to the switcher 137 of the system 13 on the normal program side. When the transmission control function is also moved to the news system 14 side, the switcher 137 is also under the control of the news APS device 144, and the news information output from the news transmission switcher 147 is also switched from the switcher 137 to the main line. Sent out, which enables on-air.

  In the above configuration, the flow of processing of the news DS device 143 in the news master transmission device 14 will be described with reference to FIG.

  First, when there is a news frame organization start request from the operator (S1), an instruction to transfer to the news side transmission control is sent to the DS device 12, and the transmission control is transferred to the news side system 14 (S2). After the transfer is completed, the news frame is reviewed (S3) and increased or decreased as necessary (S4). Subsequently, the content used in the frame and its transmission time are determined (S3), and set in the APS device 144 (S4). Whether or not further reorganization is necessary is determined from the status of the news information, and whenever the reorganization start request is received from the operator, the above steps S4 to S6 are repeatedly executed (S7). If there is no request and there is a news end instruction from the operator (S8), a news end notification is sent to the DS device 12, and the transmission control is transferred to the normal program side system 13 (S9).

  According to the system configuration described above, it is possible to change the news program frame relatively easily and fluidly by deviating from the normal program frame, and flexibly change the program organization according to the changing news content and progress. it can.

  Note that the present invention is not limited to the above-described embodiments as they are, and can be embodied by variously modifying the constituent elements without departing from the scope of the invention in the implementation stage. For example, the information can be used not only for news but also for sending other information that requires urgent action, such as time change or extension of a sports program.

  Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements according to different embodiments may be appropriately combined.
